[sdiy] Roland MC303 replacement sequencer buttons

[julian schmidt]

Hello,

I've got a friends mc 303 here to do some fixes.
Anybody knows where to get the sequencer button caps as replacement parts?
on 2 of the caps the plastic top is broken off from the base. :-/

the caps I mean are the black and white ones on this photo
